So I limped it

[BackNBlackTJ]

I limped my 04' big time yesterday, can't say I'm overly surprised... it's got 265k on the stock internals and I'm not nice to it.

I ducked out of a line of trucks to pass them, when I matted the throttle the truck accelerated hard then it felt like it dropped anchor, the RPM jumped up, but the throttle felt flat, the check engine lit up, and the DIC said "range shift disabled". After I got it off the highway and shut it down, it shifted and ran fine but I wasn't pushing it either.

When I pulled the codes, there was 0700 = Trans Controler Sys. error / 0735 = Fifth gear ratio error...


How long do I have?
I probably won't be able to get it out to Mike until January...

dude i limped my tranny over 50 times. its not the end of the world. it just gets a little weaker every time you limp it.:thumb:

 

[TeaBagger2006]

dont worry too much. just ease up on her and you will be good for a while. but it will be easier to limp now

 

[Bustedknuckles]

I only limped mine 4 times before it died completely......

Me and my heavy right foot are coming to see you soon for another trans... Not going as big on this trans, not as much power in this truck... it's mainly my daily money maker and towrig, spends most of it's life hooked to a trailer.

Hey guys. This is my first diesel and my trans seems to shift weird. I don't know anyone with another diesel so I don't know if it's normal or not. Every time I mash the throttle it takes forever to change gears. I did some research here and I guess it's called a "flare shift" ??? Is that the same as limping or does it go to neutral when it limps?? I am all stock except edge cts. It doesn't show any codes and I have done the
Relearn a couple of times. Will the transgo jr help or am I in need of a rebuild??
Thanks guys.

It's an 08 LMM with 50k miles

Have you drove around normal on every level with the edge for at least 50 miles through town per level?

 

[Mike L.]

How old is the fuel filter?

 

[08dmaxltz]

I haven't replaced it yet. Do you think the fuel filter could affect the transmission? I just finished changing the oils. Tcase,engine,trans,diffs

Yes I have left the edge on 3 for about 3,000 miles.

 

[LWATSON]

Throttle position is off with a dirty fuel filter, this in turn makes your trans shift bad. If I forget to turn my liftpump on and run my truck hard on the race tune it drains the fuel rail and shifts terrible.

 

[Dirtymax03]

08Dmaxltz Thats exatly how I know its time 4 a new fuel filter

 

[08dmaxltz]

Okay I will be adding the filter to the list... So what is limping the tranny??

 

[BackNBlackTJ]

Mike can explain it better,

but basically the trans controller goes in to a failsafe (limp mode) when problems occur, for instance I severely over torqued 5th gear going up hill passing semis at WOT and limped 5th gear...

it actually felt almost like the trans downshifted, it's hard to explain... it went from pulling hard to bearly able to maintain speed in an instant...

Closest thing I can equate it to, was when I drove trucks I actually had a pressure plate go soft on me, it slipped the clutch on and off for 4-5 miles before the clutch completely can apart on me... power was available but I just couldn't apply it.

 

[Dirtymax03]

Short answer is it takes power away from the engine and make the trany so the trany doesent burn clutches and stuff if that helps

It felt like it downshifted because it did. When the TCM detected the slip in 5th, it downshifted to 3rd and locked it there until you cycled the ignition.

 

[08dmaxltz]

Thanks guys!!! Just changed the fuel filter and wow! It drives like a completely different truck!!! The guy before me must have
Never changed it!

Thanks again!
And sorry to the OP I wasn't trying to hijack (thought my tranny was going)

 

[BackNBlackTJ]

So Thursday I done it again...

Damn-it

this time I wasn't standing on it, I was just steady throttle on a long on-ramp...

might be time to park it till I can get out to Mike for a re-build...

Yesterday morning I finally got a chance to mess with the truck... been driving my GMC the last couple days...

pulled codes 0843, 0875, 0700, 0735...

700 and 735 I'm familiar with the other two I had to look up...

What does....

-843-"Trans fluid pressure sensor/switch A circ HI"
and
-875-"Trans fluid pressure sensor/switch D circ" mean?

 

[Mike L.]

Change the spin on. Think you have serious problems here.
